The Museum of Science and Industry is the largest science museum in the Western Hemisphere! Housed in the only remaining building from the 1893 World’s Fair, MSI is a Chicago must-see! You’ll experience 14 acres of mind blowing, hands-on exhibits and have the chance to navigate through a mirror maze; manipulate a 40-foot tornado; climb aboard a World War II German submarine; take a run in a human-sized hamster wheel; descend into an Illinois coal mine; board a 727 hanging from the ceiling; transmit your pulse to a 13-foot, 3-D, beating heart; and much more! It’s fun and interactive! MSI It’s not a place where you walk around quietly and observe. No way! You get involved in the fun—and learn by doing. See your blood running through your veins, dive and surface a submarine or create an avalanche! It’s all only at MSI, Looking to host a special event, meeting or reception? We offer over 8 different and unique spaces throughout the museum that can be used alone or in combination with each other from intimate groups of 20 to the entire museum for 12,000 guests. Our on-site event planners will work with you on every detail.
